Abstract: An operating system switching method for use in an electronic device is provided. The method includes the steps of: determining whether the first operating system receives an operating system switching command at time t1; storing first status data to a volatile memory and a non-volatile memory when a first operating system enters a non-operating state from an operating state based on the operating system switching command; writing second status data stored in the non-volatile memory to the volatile memory; and controlling the second operating system to enter the operating state from the non-operating state and recover to the operating status at time t2 based on the second status data stored in the volatile memory, wherein time t2 is earlier than time t1.

Abstract: A method for counting steps and an electronic apparatus are provided. The method includes the following steps: obtaining first three-axis accelerating values of the electronic apparatus; removing a specific ratio of an acceleration of gravity from the first three-axis accelerating values to generate second three-axis accelerating values; calculating inner product values and outer produce values according to the second three-axis accelerating values; determining whether a user of the electronic apparatus is in a walking status; if yes, setting the inner product values as reference values; if no, setting the outer product values as the reference values; calculating a number of steps corresponding to the second three-axis accelerating values according to the reference values.

Abstract: A temperature control method and an electronic device thereof are disclosed. A temperature control method applicable to an electronic device comprises the following steps. A power-consumption vs. temperature lookup table is provided, which records a plurality of thermal zones and a plurality of power consumption budgets corresponding thereto. An initial power consumption budget is obtained from the power-consumption vs. temperature lookup table based on an initial thermal zone value. The power consumption modes of the plural processing units are dynamically regulated according to each detected duty basis of the processing units, and the initial power consumption budget. The power consumption budget is dynamically changed according to a detected temperature of the electronic device and the power-consumption vs. temperature lookup table.

Abstract: Multi-display electric devices and operation methods thereof are provided. The operation method is applicable to a multi-display electronic device including a screen, a touch-sensitive screen, and a processing module. A window is displayed in the screen, and a thumbnail corresponding to the window is displayed in the touch-sensitive screen by the processing module. The window is operated according to a touch-control operation command received on a display area of the thumbnail by the processing module. Therefore, the window on the screen may be operated via the touch-sensitive screen, to increase user convenience.
